Why you SHOULD ALWAYS have a fire extinguisher handy when working on the 928 fuel sys
Bad afternoon yesterday (Sunday). Working on the fuel system on my Cashmere 78. Testing pressures and working through the system. Jumped the fuel pumps and let the system run to clear the pipes for about an hour.
Connected the coil wire back and tried to start the car - saw flames - ran for the extinguisher and put it out all in less than a minute or so. Some residual fuel was laying in the valley and ignited. Small fire that was NOT being fed by fuel under pressure.
I was very lucky and the result was a few melted rubber hoses, a crinkled section of wire harness and a mess of powder.
The extinguisher saved the engine and the car.

928 Owners are ".....a secret sect of quietly assured Porsche pragmatists who in near anonymity appreciate the prodigious, easy going prowess of the 928."
When I work on the fuel system upon initial start up I have the car outside, a garden hose with water running and me holding it while someone else cranks the motor and last time I also disconnected the coils during the initial cranking period [about 10 seconds]. Learned that lesson the hard way after doing the inlet manifold in 44C heat in one afternoon/evening. I was so exhausted I forgot to tightened the test gauge nut on the fuel rail. The engine bay was covered in petrol but fortunately for me it did not ignite.
I suspect that looks worse than it is but nonetheless it still looks bad enough- doubtless you will have it sorted quickly- fingers crossed.
So sorry for you Roger, that's a bummer, glad to hear all OK with you and the overall car and garage
I've heard that you need to remove the powder ASAP, a good reminder for me to get another 10 # Halguard for the bench
not sure if congrats are in order, but this could have been ALOT worse! so congratulations on getting that fire
out so quickly. sure you will get it sorted in no time. now go make a cocktail and buy a lottery ticket. strike that:
buy the ticket first; no drinking and driving. stay safe.
Wow that was a close call Roger,
one errant spark and poof.
This looks mostly cosmetic in nature but it will force you to do an intake refresh.
By the way the spray engine cleaner called engine gunk is also flammable.
I was spraying down a running engine after fitting cam tower gaskets,
and one of the ignition leads was leaking. one second I was spraying the next I heard a big whoof.
lucky I had the charged shop hose next to the car,
I grabbed it and the fire went out just about as fast as it had started.
My hair did suffer but thats all.

I think this thread could also be titled:
Why the parts guy SHOULD NEVER work on his own car!
or:
Why I stock and sell Halon Fire Estinguishers, ONLY!
Counting the blessings here Roger. Way to go on the quick footwork to get that extinguisher! Could have been a lot worse than just a car. Hope you get it back together and running properly soon.

Might be why he didn't call me on Sunday when he was working on it. I've got 4 Halon or Haliton tanks close to anything I'm working on. I keep giving Roger **** because he doesn't call me on the weekends when he's working on his own cars. I think that may change now.
Dude, seriously. I do like my weekends off but hell. Like I told you..............I'm here for this sort of thing, just call. It's called friendship for a reason.
